Specification of Letters Patent.

Application filed Meyfi'il, 1918. Serial No. 236,740.

To all whom it may concern Be it known that l, FRANK Became, a

vented-certain new and useful Improvementsin Annular Ball-Bearings, of which the following is a specification.

The principal objects of the present invention are, first, to provide an improved, simplified and convenient construction and combination of sheet metal parts which can be readily assembled into the form of an inexpensive, durable .and reliable annular bearing having two circular rows of balls and adapted to take a radial-load together With end thrust in two directions; second, to provide for taking up slack or play between theparts in order to avoid noise and looseness; third, to provide simple means for maintaining the parts in assembled relation, and fourth. to provide an efiicient, acceptable and comparatively inexpensive annular bearing of the stamped or pressed sheet metal variety.

To these and other ends hereinafter set forth the invention comprises the improvements to be presently described and finally claimed.

' Figs. 4, 5, and 6, are transverse sectional views of parts of an annular ball bearing embodying modifications of the invention.

Fig. 7, is a transverse sectional view of a bearing embodying another modification oi the invention, and FFigi. 8, is a side view of elements shown in Referring to the drawings there are two centrally perforated dished-disks 1, arranged back to baclr with their daring portions 2 extending in opposite directions.

These disks 1 may be stamped, punched, pressed or otherwise fabricated from sheet metal. 3, is. a ring arranged through the disks 1 and havin outwardly daring ends 4, respectively con ontin the inner daring surfaces ct the disks. his ring can be made of sheet metal. There are two circu lar rows of balls 5 arranged respectively be tween the outer flaring surfaces of the ends of the ring 3 and the inner flaring surfaces of the disks. The central opening in the disks is large enough to permit the disks to be passed over the endsot the ring and when the disks are shifted or moved inward. from the ends of the ring, suficicnt space is pro vided forthe insertion of the balls. There is a split ring interposed between the disks for the maintenance out the assemblage. In Figs. 1 to 4:, this split ring 6, is a spring ring and it is circular in cross-section, whereas in Fig. 5, this split spring ring 6, is of generally wedge-like cross-section. However, in all these figures the split spring ring not only maintains the assemblage but takes up any slack or play between'the parts, thus avoiding noise and looseness.

Referringto Figs. d and5, 7 is a band with inturned edges that may be applied around the periphery of the disks. edges of the band '2', or more accurately, one of them, can becrimped in after the application of the band. The split spring ring 6, in Fig. 6, is oblong in cross-section and is seated between the ontwardl extending flanges of. the daring ends of t edislrs and it serves to maintain the assemblage. The split ring need not be a spring rin and it may have more than one split. Sue a two; part, non-spring ring 6, is shown in Figs; 7 and 8, and its parts are confined by the band if, in order to cause it to maintain the assemblage. lit will, of course, be .understood that the split s ring ring can be pull: or sparring in place a ter the other parts of the caring have been assembled, but of course prior to the applicationoi theband '74. It may be remarked that the split ring takes a part in resisting end-thrust within the limits or the capacity of the bearing.

What T claim is: 1. An annular ball bearing comprising, in

. combination, two sheet metal centrally per iterated dished-dislts arranged back to back with theirflaring portions entendin in opposits directions, a. sheet metal ring arranged through the dislrs and having outwardly flaring ends respectively controntin. the inner daring surlacesp't the dislrs, and

adapted tor passe e through the openings the dislrs, two circular rows oi balls ararid Patented Dec. 3, rare.

' rec lltllli ranged respectively between the enter darring curiae-es oi the ends of the ring and the inner flaring surfaces of the disks, and a split ring interposed between the disks to maintain the assemblage.

2. An annular ball bearing comprising in a combination, two sheet metal centrally perforated dished disks arranged back to back with their flaring portions extending in opposite directions and provided with flanges, a sheet metal. ring arrangen through the 10 disks and having outwardly flaring ends re 15 tween the outer flaring surfaces of the ends of the ring and the inner flaring surfaces of the disks, and ii ring interposed between the flanges, snhstantiaily as described.

3, An annular ball has 'ing comprising, in combination, two sheet metal centrally perforated dished-disks arranged back to back with their flaring portions extending in 01)- posite directions, a sheet metal ring arranged through the disks and having o11t Wain ll} flaring ends respectively confronting" the inner flaring: surfaces of the disks, and adapted for passage through the opening in the disks, two circular rows of balls arranged respectively between the outer laring surfaces of the ends of the ring and the inner flaring surfaces 01 the disks, a split ring interposed between the disks to maintain the assemblage, and a band covering the ring and providing a cylindrical exterior sn rii'a FRANLQI BEEMER.
